RAILROAD-TRACK SCALE.

No. 824,591. Specification of Letters Patent. Patented June 26, 1906. 4

Application filed January 14, 1905. Serial No. 241,105.

To all whom it may c0ncernr Be itknown that I, WILLIS H. SARGENT, acitizen of the United States, residing at St. J ohnsbury, in the countyof Caledonia, State of Vermont, have invented certain new and useful Imrovements in Railroad Track Scales, of w oh the following is adescription, reference being had to the accompanyin drawings and to theletters of reference marke thereon. My invention relates to animprovement in railroad-track scales of the well-known Fair- .bankstype; and it consists in novel means for supporting thev main levers,for supporting saddle the toffbe detach and adjusting the pivots of theextension-1e vers, and for connecting the extension-levers: It alsoincludes a feature which is believed to be novel-namely, the provisionof a separable stand for the main lever for allowing the ready removalof the latter.

The invention also consists in-variousmatters hereinafter described, andreferred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a perspective detail view illus trating the gianeralarrangement of the'framesections of t :ments.

Figs. 7 and 8 reresent, respectivellyl), end and side views oft e link and b cksconnecting two extension-levers. Fig. 9 is' a," side elevation, partlyin sec tion, of, a scale embodying the invention. 'Fig.

10 is a-plan view, and Fig. 11 a cross-section of thescale on the line11 11 of Fig. 9.

In the drawings, referring first to Figs. 1 and -2, it represents themain levers, suspend ed by loops 9 andlinks f from suitable supports,comprising, posts. a a, cast solid with the base (1' and connected withthe sts sup- -portingthe opposite main lever, y angle I 110118 a: Thecross-bar '5' of the supportv from ,which-the loop-link f .-is hung isremovable from, the rest Y of, the {thus allowing 1 removed. Thiscross-bar b is chamfered oii V at each end, as shown att a, so as to fitinto sockets c c in the posts a a. A slight shoulder :2: is provided ateach end of the chamfer or bevel, which shoulder drops down betweenmotionof the crossbar.

To prevent dirt or water from collecting around the pivots in the mainlever h, a removable shield e is provided which fits up closely aroundthe posts a a and is held in placedby lugs g, which are supported on thease Figs. 3, 4, 5, and 6 represent in detail the manner of supportingan. extension-lever, as At one 'en ofthe lever is a nose-iron k,

earing a pivot I. For various reasons in means of adjusting this pivotboth vertically and horizontally and at the same time securing it firmlyin position. This is accomphshed by making the opening in the noseironlarge enough to permit of putting gibs above and below the ti end of thelever j. Fig. 4 is an end view of t e nose-iron, and Fig. 3 a section online 1) p.- Figs. 3 and 4 show a thick gibm above and a thin gib nbelow, thus locating the pivot edge at some distance above the lever.Figs. 5 and 6 show the ,reverseof this, n being the thick piece and/m,the thin one,'thus lowering the position of the pivot with relation tothe lever. The nose-iron 7c is recessed at 0, Fig. 3, and at 0, Fig. 6,and the 'bs are-shouldered correspondingly so that t .bytalring off theentire noseiron, which is secured in place by a set-screw r or T. Itwill be'noticed inFigs. 4 and 5 that the 11 per gibs m and m arediamond-shaped and t' at both thenose-iron and the lever are shaped. tomatch. The object of this is to reserve the to prevent the pivot lfromswinging around having 'pivot may be vertically locatedwhereverdesired,and the lever may be sealed by mo 'the nose-iron horizontally, ,and thewhdl d firmlysecured by theset-screw aiidahemaia later the posts a a,and thus prevents any endwise manufacturing it is desirable to have someey cannot be removed except alinement of the nose-ironwitht 1e lever anddiagonall It will be readily'seen that by ifierent thicknesses. of gibs'the roe . InFigs. 7 and 8 are shown details for con Inecting' theextensioh-levers w and j. shown, is, and s" are nose-irons, respectively-attached to the'npp'erjand lower levers '2' and w and each carrying apivot, (marked, respectively, z and z.) Resting on the edges of thesepivots are bearing-blocks u and u, and these'are connected by means of alink t, which passes around. both and allows the bearing-blocks, toadjust themselves so as to make a bearing along the whole length of thepivots.

It has been found that the details of construction hereinbefore referredto are of con siderable practical importance in the construction ofrailroad-track scales, and I wish to cover suchdetails as broadly aspossible.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent,is

1. In a railroad-track scale, the combination with the main lever withloop and link for hanging the same,v of a support comprising postshaving sockets in their upper ends,a

crossbar beveled off at each end to fit said sockets and having ashoulder adjacent the bevel; substantiallyas described. I

2, In a railroad-track scale, the combina- I seasei sockets, and havinga shoulder adjacent the bevel, and a removable shield as e having on itsunder side lugs to engage withthe base-' piece supporting the posts;substantially as described. v a

' 3. In a railroad-track scale,'the combination with a main lever andextension-levers, and means for supporting the tip ends of said Iextension-levers, comprising a nose-iron horizontally adjustable on saidlayer, a pivot carried by said nose-iron and removable gibsof varyingthicknesses for adjusting the vertical position of the pivot withrespect to thelever substantially as described.

In testimony whereof I allix my signature in presence of two witnesses.
